  • the invention is not limited to objects approaching or falling into the water.
  • the systems and methods disclosed herein may be applied to objects approaching or falling into the earth, and not just water.
  • Seismic data may be collected from vessels that operate in the assumed body of water, such as the sea or ocean. This collected data is recorded prior to the assumed time of the crash, during the crash, and after the crash up to a predetermined number associated with time.
  • the predetermined number may include any number of seconds, minutes, hours, days, weeks, months, etc.
  • the collected data may be recorded prior to and after the crash up to a minimum of fifty hours.
  • a direct wave and a refracted wave may be recorded by the receivers in the streamer, and with reference to FIG. 8, a direct wave and a refracted wave may be recorded by one or more ocean bottom node (OBN) devices.
  • OBN ocean bottom node
  • different formulas may be used to estimate these distances based on direct waves or refracted waves, and this is part of the specific processing for the streamer and OBN; to obtain accurate estimation of SRi, accurate water velocity variation with depth is required. In the second situation, consideration must also be given to the location of the crash at a large distance from the survey area.
  • a deep sound channel such as a sound fixing and ranging (SOFAR) channel
  • SOFAR sound fixing and ranging
  • Water velocity analysis is required to be performed on the collected seismic data to determine water velocity variation with depth, and to determine if there is a layer of low velocity in the water (SOFAR channel). If the presence of this layer is detected, it must be evaluated how this is coupled to the streamer spread or OBN grid of receivers.
  • An example of water velocity analysis is illustrated in FIG. 9. This is based on measuring the semblance on common midpoint (CMP) gathers that normal moveout (NMO) corrected with different velocities.

  • any reflection coming from it will be showing a rather large anomaly. Moreover, this reflected signal will likely not indicate sand or mud and will rather exhibit certain characteristics. In some examples, if a seismic survey was recorded over an area where a plane crashed, and the plane did not disintegrate in very small fragments, the recorded signal may appear as seismic diffractions, because the acoustic impedance contrast between plane (metal) and earth sediments is very high.
  • Object location may be accurately approximated and thereby improved by transmitting the signals received from different surveys from a vessels and hydrophones and based on the difference in acoustic impedance including the velocity and density of the water.
  • the source of energy is the object, or plane, itself when it makes contact with the surface of the water.
